The second cour of the anime adaptation of the shoujo manga Red River began streaming new episodes weekly on Crunchyroll. Alongside the episodes, the series released creditless versions of its opening and ending sequences. The opening, titled "Akatsuki no Hoshi" and performed by Nana Mizuki, is available without visual overlays. The ending theme, "flow feat. Yuko Ando" by Ryu Matsuyama, was similarly released in a creditless format. Both musical tracks have also been made available as digital singles for streaming and download. These releases were posted by VAP Official on YouTube, which noted the availability of the videos on its channel.
